Abstract:
OBJECTIVE: To establish a RP-HPLC method for the determination of pamidronate disodium. METHODS: The determination was performed on C18 column with acetonitrile-0.4% sodium hydroxide solution of EDTA-Na2 (14∶86) as mobile phase at a flow rate of 0.6mL?min-1,the sample size was 10?L and the detection was performed by fluorescence detector with excitation wavelength at 395nm and emission wavelength at 480nm. RESULTS: The linear range of pamidronate disodium was 7.2～16.8?g?mL-1(r=0.999 8,n=9),the recovery rate was 100.11%(RSD=0.7%, n=9). CONCLUSIONS: The established method is simple and accurate.
